Letters Patent No. 101,700, dated April 12, 1870.

The Schedule referred to in these Letters Patent and making part of thesame To all whom it may concern Be it known that I, J om; A. BANGROFT,of the city and county of Worcester, and Commonwealth of Massachusetts,have invented certain new. and useful Improvements in Street-Sprinklers,of which the following is a full, clear, and exact description,reference being bad to the accompanying drawing forming part of thisspeeilication,.and which represents a plan view of so much of astreet-sprinkler as is necessary toillnstrate my presentlint-pronements, a part of the sprinkling-reservoir being shown brokenaway to illustrate the construction more fully.

To enable those skilled in the art to which my invention belongs to makeand use the same, I willproneed to describe it more in detail.

The nature of my invention consists-- First, in the combination withadivided sprinklingreservoir, of three independent supply-pipes, ashereafter explained.

Second, in the combination and relative arrange ment, with thesprinkling-reservoir, of partitions and removable caps, as and for thepurposes hereafter explained.

Inthe drawing- A represents a section of the bottom of the watertank,having three openings, at a a, into whichareinserted the conducting orsupply-pipes B G D, which conduct the water to the sprinkling-reservoirE.

The sprinkling-reservoir E is made in three sections or compartments, FG H, each being provided with openings in the bottom, stopped bysuitable screw-plugs or caps, b b b b, and the sections or compartmentsF and H each having similar openings or outlets and caps or plugs, b, attheir outer ends.

These .openings or.outlets are for the purpose of cleansing thesprinkler from any sediment or obstructions that may accumulate therein,and which is done by removing the screw-plugs and opening the gates, andletting on a full head of water, the force of which, entering throughthe pipes B O D, and passing out through the outlets stopped by theplugs b, carries out any sand, dirt, or other sediment or obstructionsthat may have accumulated or lodged in the sprinklingreservoir.

Each opening a is to be provided with a separate valve, so that it canbe closed by the driver at pleasure, to shut off the water from one orall of the compartments,as may be desired.

It will be seen that, by making the sprinkling-res- :rvoir withdivisions, d, to form sections or compart- 3 ments, as shown, the wholeor any portion of thewidth of the street may be sprinkled, as maybedesired. For instance, if it is desired to-sprinkle only a portion ofthe street,.on the right-hand side, the driver opens the valve to pipeB, which allows the water to pass into the compartment H, and only thatpart of the street will begsprinkled.

To sprinkle the left-hand side of the street, the operation would bereversed, the valve to pipe D being, o ened, andthe water conducted.through the same to compartment F, the'other valve remaining closed;while, if it was desired to sprinkle a portion of the center of thestreet, water would be let into pipe '0, and distributed through thesection, G of the sprinkler upon that portion of the street.

In sprinkling streets, it is often desirable to stop the flow of waterfrom one or both sides of the sprinkler, especially when driving nearthe curb-stones, or

through narrow streets, to avoid wetting carriages and the clothing ofpersons on the adjoining sidewalks or in carriages standing at the sideof the street,

and also to avoid startingrestive horses, which, it Will be seen, canreadily be done with my improved sprinkler, and that, too, in a moreconvenient and desirable manner than it can be done by the sprinkler-inwhich side guards are used, as in the sprinkler patented to Bancroft andYetter, March 3d, 1868, as the assignees of L. F. Bancroft, and nponwhich sprinkler my invention is an improvement.

By said L. F. Bancrofts arrangement, the side guards, when down,arestruck by the water, causing a hissing sound; whereas, by myinvention, such objection is entirely obviated, while at the same time agreat saving of water is efiected.

Having described myirnprovements in street-sprink- Iers,

\Vhat I claim'therein 'as new and of my invention, and desire to secureby Letters Patent, is-

1. The combination with the sprinkling-reservoir E, of thedivision-plates or partitions d and independent supply-pipes B, O, andD, substantially as and for the purposes stated. I

2. The'coinbination with the sprinkling-reservoir E, of the partitions dand'stop-plugs or caps, as shown and described. JOHN A. BANOROFT.
